X-Treme Board™ is an ecological alternative to gypsum, wood, and cement based building products.

X-Treme Board™ is manufactured with a patent pending process and formula, using primary components of magnesium oxide and magnesium chloride. The manufacturing process uses less than 50% of the energy consumed to make a comparable Portland cement based wall board. X-Treme Board contains a minimum of 5% transferred post-industrial recycled material, and 100% of our manufacturing post-industrial waste is recycled into future production runs.

No raw materials or scrap materials are ever wasted or put into a landfill. X-Treme Board™ may contribute to LEED credits MR8, minimum EQ, EQ 3.1 (EQ plan during construction) and MR4.1, (materials with recycled content).

Cargo Ship

X-Treme Board™ is manufactured in Asia, and shipped to you on large container ships. Research has shown that the carbon footprint of shipping one pallet of X-Treme Board to the USA is approximately equivalent to driving the same pallet about 25 miles in a pickup truck to the jobsite.

X-Treme Board™ is non-nutrient for fungus when tested under ASTM D3273, because of its high content of magnesium oxide and magnesium chloride. In other words, it naturally will not grow mold or mildew, solving one of the biggest issues of construction in wet areas such as showers and tub surrounds. In addition, X-Treme Board™ contains no VOCs or harmful silica, making it safe for the installer as well as the end-user. X-Treme Board™ has been successfully used in construction for the chemically sensitive.

X-Treme Board™ is waterproof. It will not swell, delaminate, warp, or disintegrate when exposed to a wet environment. Remarkably, X-Treme Board™ is also water vapor permeable. This allows X-Treme Board™ to be used as a wall-board in construction where breathable walls are specified.

X-Treme Board™ received the Class 1 or Class A flame and smoke rating when tested under ASTM E84. This means that it does not contribute fuel to a fire, and does not produce flame or smoke when exposed to fire. In international testing, 1/2” X-Treme Board™ has been approved as part of a two hour fire assembly.
